I am creating a tab view and linking those tabs to 4 different classes but my project is not running due to the following errors:

This is my way to add view group to tabs

private TabHost     tabs = (TabHost) findViewById(R.id.tabhost);
        tabs.setup();

        TabSpec HP_tab = tabs.newTabSpec("tab_six_btn_tab");
        HP_tab.setContent(R.id.scroll);
        HP_tab.setIndicator("HP World");
        tabs.addTab(HP_tab);

        TabSpec notebook_tab = tabs.newTabSpec("tab_one_btn_tab");

        notebook_tab.setContent(R.id.Notebook_Tab);
        notebook_tab.setIndicator("Notebook");
        tabs.addTab(notebook_tab);

        TabSpec desktop_tab = tabs.newTabSpec("tab_two_btn_tab");
        desktop_tab.setContent(R.id.Desktop_Tab);
        desktop_tab.setIndicator("Desktop");
        tabs.addTab(desktop_tab);

        TabSpec pos_tab = tabs.newTabSpec("tab_three_btn_tab");
        pos_tab.setContent(R.id.POS_tab);
        pos_tab.setIndicator("POS");
        tabs.addTab(pos_tab);

        TabSpec Promotion_tab = tabs.newTabSpec("tab_four_btn_tab");
        Promotion_tab.setContent(R.id.Promotion_Tab);
        Promotion_tab.setIndicator("Promotion");
        tabs.addTab(Promotion_tab);

        TabSpec Hard_tab = tabs.newTabSpec("tab_five_btn_tab");
        Hard_tab.setContent(R.id.HardBranding_Tab);
        Hard_tab.setIndicator("Hard Branding");
        tabs.addTab(Hard_tab);

        tabs.getTabWidget().getChildAt(0).getLayoutParams().height = 30;
        tabs.getTabWidget().getChildAt(1).getLayoutParams().height = 30;
        tabs.getTabWidget().getChildAt(2).getLayoutParams().height = 30;
        tabs.getTabWidget().getChildAt(3).getLayoutParams().height = 30;
        tabs.getTabWidget().getChildAt(4).getLayoutParams().height = 30;
        tabs.getTabWidget().getChildAt(5).getLayoutParams().height = 30;
        Display display = getWindowManager().getDefaultDisplay();
        display.getWidth();
